FRANCIS-LYONS AND ALBERT S. LYONS, OF NEW YORK, N. Y.

FAN.

SPECIFICATION forming part of Letters Patent No. 625,179, dated May 16,1899.

Application filed March '7, 1899.

T0 at whmn it may concern: i

Be it known that we, FRANCIS LYONS, residin g at the city of New York,borough of Brooklyn, county of Kings, and ALBERT S. LYONS, of the cityof New York, borough of Manhattan, county of New York, State of NewYork, citizens of the United States, have invented certain new anduseful Improvem entsin Fans, of which the following is a specification.

Our invention relates to certain improvements in fans; and the object ofthe invention is to so apply to the stick ofthe fan which is held in thehand of the person making use of the same, mechanism whereby motion maybe imparted to the fan without the usual and tiresome exertion of movingthe arm or hand to and fro.

The invention is illustrated in the accompanying drawings, forming apart of this specification,and the subject-matter for which protectionis desired is pointed out in the claims at the end hereof.

In the drawings, in which the same parts are indicated by the sameletters of reference in the several views, Figure 1 is an elevationshowing the manner of making use of the fan. Fig. 2 is a verticalhorizontal section through the cylinder receiving the stick and theparts containing the mechanism for ionparting motion to the fan; andFig. 3 is a section on the line 3 3, Fig. 2.

Referring to the drawings, Aindicates the fan, which obviously may be ofany design or form and of any suitable material, and B indicates thestick or holder, which also may be of such material and form as tastemay dictate. The stick B is secured in the lower end of the part 0,which is preferably made of metal on account of the superior finish thatmay be given to metal by nickel-plating, 8m. Projecting laterally frompart 0, near its upper end, is the tube D, open at its inner end andclosed at its outer end. The tube D is fixed in position within the part0 and is adapted to receive the spiral spring E, as shown. The part G isperforated coincident with the open inner end of the tube D, so that thepiston F may be inserted into said tube. The piston Fis hollow, but isclosed at its outer end, its inner end being in contact with the spiralspring E within tube D, and on the inside of said piston there issecured a rack d, as shown.

The fan is fixed by any suitable device,

semi No. 708,073. on model.)

such as clamp G, to the spindle g, which passes through a hole in thetop of part 0 and extends below the tube D and through the guide 0,fixed within the part 0. The spindle g is provided with a pinion e,whichis adapted to cooperate with rack d. Below and above the pinionethe spindle g is provided with bearing-collars b, which also serve tomaintain the pinion e in proper relation to rack d. The tube D andpiston F are slotted, as shown, respectively, at d f, in order that thepiston F when forced forward by the thumb may not have to work againstan air-cushion confined within tube D. The perforation or slotting ofthese parts is found to be very desirable in the operation of thedevice, for without such provision the movement of the piston would beslow and hard and the wear on the parts much increased.

When the stick or holder B is held in the hand and the piston F isforced in by the thumb, the spring E is compressed and rotary motion isimparted to the spindle 9 through the rack and pinion d 6. When thepressure of the thumb on the piston is removed, the expansion of thespring E will force the piston outward and thus impart to the spindle ga reverse rotary motion.

Having thus described our invention, what we claim is- 1. Thecombination with a fan and its stick or holder, of a hollow part towhich the stick is attached, the said hollow part provided with alaterally-projecting tube, a spiral spring within said tube, a pistonfitting in said tube and provided in teriorly with a rack, a spindle towhich the fan is connected andwhich is supportedin said hollow part, anda pinion on said spindle adapted to cooperate with said rack.

2. The combination with a fan and its stick or holder, of hollow" part 0having a perforated lateral tube D, spindle 9 provided with pinione,-spiral spring E, and a hollow pis ton F provided interiorly with arack d with which pinion e cooperates.
